Key result
Previous right bundle branch block (OR 11.52; 95% CI 2.63-50.44) and LVOT-EI >0.3 (OR 3.07) were independent predictors of permanent pacemaker need after TAVR with the STHV-34 device.
Why the study?
Predictive factors of permanent pacemaker implantation had not been sufficiently evaluated in the context of the 34 mm self-expandable transcatheter heart valve.
Cohort (n=130)
Yes
In patients undergoing TAVR with the 34 mm self-expandable device, previous right bundle branch block and pronounced LVOT eccentricity index are strong independent predictors of needing a permanent pacemaker, whereas membranous septum length and implantation depth were not.
Prior RBBB may inform PPM risk counseling in STHV-34 TAVR; leaves open prospective validation and impact on device selection.

Veulemans et al. (2020) conducted a cohort in Transcatheter Aortic Valve Replacement (TAVR) (n=130). Previous right bundle branch block (RBBB) vs. Absence of previous RBBB was evaluated on Post-procedural permanent pacemaker (PPM) implantation (OR 11.52, 95% CI 2.63-50.44, p=0.001). Previous right bundle branch block (OR 11.52; 95% CI 2.63-50.44) and LVOT-EI >0.3 (OR 3.07) were independent predictors of permanent pacemaker need after TAVR with the STHV-34 device.
